TURBINE Specication of Letters Patent.

Patented April 27, 1909.

Application led August 3, 1905. Serial No. 272,621.

l'o all whom it may concern:

Be it known that I, CHARLES LEMALE, a citizen of the Republic of France,residing in Paris, France, have inventednew and useful Improvements inTurbines, of which the following'is a specication. i

The present invention consists of improvements in gas-driven turbines,and relates more particularly to turbines wherein the motive fluid isobtained by the combustion of a gaseous mixture under. a continuouspressure in special chambers, and in which steam is projected on to theblades of the turbine.

The embodiment of the invention shown in the sin le figure of thedrawing comprises the combination of a high-temperature gas nozzle Hwith a steam nozzle I, these being both directed on to the disk J. Inthis figure the steam is produced in the water jacket K surrounding thecombustion or eX- 2 plosion chamber L and the high-temperature L nozzleH. The Water in the jacket is in a very thin body, so as to betransformed quickly into vapor. The steam collected in an intermediatereservoir or dome M expands through the nozzle I.

What I claim is A hot-blast turbine including in combination acombustion chamber for effecting combustion of a gaseous mixture undercontinuous pressure, a nozzle for projecting the products of suchcombustion under pressure upon the blades of the turbine, a steamgenerator carrying o. thin body of Water sur rounding at least a part ofsaid combustion chamber and nozzle, a nozzle for projectingr steam fromsaid generator on to the blades ofthe turbine, and an intermediatereservoir between the steam generator and said nozzle.

In Witness whereof l have hereunto signed my name this 19th day of June,1905, in the presence of two subscribing Witnesses.
